2. ### How to find the values of the constants k and c ?

f(2) = 2Â² + k (2) + c = 0 f(-3) = -3Â² + k (-3) + c = 35 Drop the functions on the left and multiply...4 - 12 + 8 = 0 9 + 18 + 8 = 35 -8 + 8 = 0 27 + 8 = 35 0 = 0 35 = 35 This checks. k = -6 and c = 8

4. ### y= a sin k (x- c ) + d rearrange for x?

Do you mean y = asin[ k (x - c )] + d? y = asin[ k (x - c )] + d Subtract both sides by d: y...d)/a)/ k Finally, add both sides by c : x = arcsin((y - d)/a)/ k + c I hope this helps!
